Solution Overview

Problem

Existing electronic devices face vulnerabilities in user authentication, as personal information can be exposed during the authentication process and is at risk of being accessed by malicious third parties, especially when data collected by external devices is not encrypted before transmission.

Innovation Solution

Generating temporary identification information using key information from both the electronic device and the external device, combined with time-variant key information, and applying a hash function to secure data transmission and prevent exposure of user identification information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user authentication is performed using personal information such as identification and password, then authentication can be completed, but personal information can be exposed to malicious third parties

Engineering Contradiction:
Improveauthentication securityVSAvoidinformation exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces temporary identification information as an intermediary that replaces personal information (identification and password) in authentication processes. This temporary identifier acts as a mediator between the user and the authentication system, allowing verification without exposing sensitive personal data to external devices or networks.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the essential authentication function from personal information by generating temporary identification data that contains only the necessary verification capability. This separation removes the harmful element (exposure of personal information) while preserving the useful function (authentication).

Inventive Principle:
Principle #2Taking out (Extraction)

2Speed

If data collected by external electronic device is transmitted without encryption, then transmission speed is maintained, but data can be accessed by malicious third parties

Engineering Contradiction:
Improvedata transmission speedVSAvoiddata access by third party
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent changes the parameter of data representation by encrypting collected data before transmission. This transformation modifies the data into an encrypted format that maintains transmission efficiency while adding security protection against unauthorized access during transit.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If personal information is stored in external electronic device for later use, then convenience is improved, but information can be extracted by hacking the device

Engineering Contradiction:
Improvedata storage convenienceVSAvoidinformation extraction through hacking
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent uses temporary identification information as an intermediary that allows the external electronic device to store and process data without containing sensitive personal information. The temporary identifier enables data association and retrieval functionality while preventing extraction of actual personal data through hacking attempts.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Disclosed is an electronic device and a method thereof, in which user identification information is not exposed because data transmission and reception are performed by using temporary identification that distinguishes one user from another user, instead of by using user identification information of an electronic device.
